Keto Apps Compared: 12 Apps on the Same 10 Criteria
Published: 21 October 2026 · Information as of: 21 October 2026 · Easy Keto. This page was written with the help of AI and published by Easy Keto.
Deutsche Fassung: Keto-Apps im Vergleich
Disclosure: This page comes from Easy Keto, the provider of one of the compared apps (Easy Keto: Low Carb Recipes, provider Martin Stein). It is therefore also advertising for our app. We present the other apps by the same rules, with their strengths.
There was no test: no app was installed or tried for this page. All information comes from the US store pages and the providers’ websites, retrieved on 21 October 2026, and is the providers’ own information. There was no expert review by third parties. Easy Keto gets nutrition data partly through the fatsecret Platform API; the FatSecret app is also in this comparison. The page contains no affiliate links and no paid mentions.
Looking for a keto app and want to know which one suits you? This page puts 12 apps side by side that are available in the US App Store and on Google Play in the US, including our own app, Easy Keto. They are compared on 10 criteria with a measurement rule that is the same for every app. Every entry has a source with a retrieval date. There is no overall score and no first place.
Key points
- All 12 apps list English in the US App Store; 8 of them also list Spanish. English only: Carb Manager, KetoDiet, Senza and Stupid Simple Keto.
- The sources name a permanently free version for 10 of the 12 apps, mostly with limits, and Senza lists no purchases at all. For Keto Manager, neither store texts nor the provider name one.
- Annual subscription items in the US App Store range from $23.90 to $119.99; many apps list several annual prices (per app in the table). Senza lists no purchases. Prices change often; the price the store shows at checkout applies.
- The stores show neither a tracking label nor ads for 5 apps: Carb Manager, FatSecret, KetoDiet, Keto Tracker and Senza.
- Easy Keto has a tracking label, shows ads in the free version and, at $44.99 a year (US App Store), is above the lowest annual price of 6 of the 11 other apps (Keto Manager: footnote 1). Details under Where Easy Keto falls short.
The 10 criteria and how they are measured
The criteria and their measurement rules are listed here, before the tables. Each one applies to every app in the same way and relies on a public source; where a cell departs from the rule, a footnote says so. Where the source says nothing, the cell says “n/a” (no information). That does not mean “no”: the feature may still exist.
| No. | Criterion | Met if … | Source |
|---|---|---|---|
| K1 | English interface | the language list in the US App Store (“Information”, “Languages”) includes English; the cell also shows how many more languages it lists and whether Spanish is one of them | AS |
| K2 | Free to use | the store text or the provider names a permanently free version, or no purchases are listed at all; a free trial alone does not count | AS, GP, AW |
| K3 | Annual price | no yes/no rating: range of all items with an annual duration in their name in the “In-App Purchases” list of the US App Store, plus whether the list includes a one-time purchase | AS |
| K4 | Net carbs | the source names a net carbs display; “limited” if only under conditions (Premium, language, region); the provider’s definition is given if it names one | AS, GP, AW, AH |
| K5 | Macro tracking | the source names logging carbs, fat and protein (or “macros”) | AS, GP, AW |
| K6 | Barcode scanner | the source names one; “Premium only” if the source says so | AS, GP, AW |
| K7 | Recipes in the app | the source names ready-made recipes in the app; creating your own recipes does not count; a number is shown only as the provider’s statement | AS, GP, AW |
| K8 | Apple Health and Health Connect | per platform: the source names the connection; “Premium only” if the source says so | AS, GP, AW, AH |
| K9 | No tracking per App Store label | in “App Privacy” of the US App Store, the section “Data Used to Track You” is missing or the label reads “Data Not Collected” | AS |
| K10 | No ads per store | neither the App Store (“Contains: Advertising”) nor Google Play (“Contains ads”) shows ads | AS, GP |
Source codes: AS = App Store page (US), GP = Google Play page (US), AW = provider website, AH = provider help center. The links are listed per app under Sources, all retrieved on 21 October 2026. Time basis: all sources were retrieved from Germany on 21 October 2026 between 01:44 and 02:17 CEST, when it was still 20 October 2026 in US time zones. Availability on Google Play in the US is approximated by the US country setting of the store page (gl=US). The App Store dates in the table “Last updated” are UTC dates. Privacy labels and ad labels are the providers’ own statements. The App Store says: “This information has not been verified by Apple.” Google Play says: “The developer provided this information and may update it over time.”
Why these criteria
When we retrieved Google’s US search suggestions on 21 October 2026, “free” came first for “keto diet app”, “best keto app”, “keto tracker app” and “carb counter app”; “keto diet app” was also followed by “cancel subscription”, “cost” and “subscription”. That is why free use and price come first (K2 and K3). K1 shows the interface languages. K4 to K8 are features that the keto apps in this comparison name in their own store texts. K9 and K10 are about your data and ads; both are shown for every app in the store.
Which apps are in the comparison
An app was only included if it is available in the US App Store and on Google Play in the US, if its store text or provider mentions keto, low carb or net carbs, and if it showed up in at least one search: the US App Store or Google Play search for “keto”, “keto app” or “low carb”, a web search or Google’s search suggestions. Not included are apps that have not been updated for more than 2 years and apps whose core is measuring blood values. This page is the English version of our German comparison and starts from the same apps; one of them lists only German in the US App Store and was replaced by the highest-ranked app in the US App Store search for “keto” that meets these conditions and was not yet included. The calorie counter apps FatSecret, Lifesum, MyFitnessPal and YAZIO are included because their store texts mention keto or low carb. The selection is not complete: other apps meet these conditions as well.
The tables sort the apps alphabetically; Easy Keto is marked as our app. The order is not a ranking.
What is not compared
Not compared are store ratings and reviews, taste and choice of recipes, the accuracy of nutrition data and databases, ease of use, offline use, web versions, whether an account is needed, and how to cancel a subscription. That would have required a test or information that is not available for all apps.
Comparison tables
All information as of 21 October 2026. Every cell with an entry names its source as a code. Prices are the US dollar amounts that the US App Store shows in its “In-App Purchases” list. This list shows at most 10 items and also includes offer and older prices; it does not say which price applies to new users. Google Play’s web page shows no list of in-app purchases with durations; the price columns therefore only use the US App Store list.

When retrieved, these help pages were blocked (HTTP 403): FatSecret and MyFitnessPal on net carbs, MyFitnessPal on Apple Health, and YAZIO on Apple Health and Health Connect. What they say is therefore not considered; the cells show “n/a” unless another source names the feature. For MyFitnessPal, the website names the “Net Carbs Mode” with Premium.
The apps calculate net carbs differently: some subtract only fiber, some also sugar alcohols. How Easy Keto calculates net carbs for the recipes on this website is explained on How we calculate nutrition values.

Where Easy Keto falls short
- Tracking (K9): Easy Keto’s App Store label names “Data Used to Track You: Usage Data”. 6 of the 11 other apps have no tracking label: Carb Manager, FatSecret, KetoDiet, Keto Tracker, Senza and Stupid Simple Keto.
- Ads (K10): The App Store and Google Play show ads for Easy Keto. They run in the free version; Premium removes them. 7 of the 11 other apps show ads in neither store: Carb Manager, FatSecret, KetoDiet, Keto Manager, Keto Tracker, Lifesum and Senza.
- Price (K3): The annual subscription costs $44.99 in the US App Store. 6 of the 11 other apps list a lower annual price: YAZIO (from $23.90), Carb Manager and Keto Tracker (each from $24.99), Keto.app and Stupid Simple Keto (each from $29.99) and FatSecret (from $38.99). Higher are MyFitnessPal (from $49.99), KetoDiet ($79.99) and Lifesum (from $99.99); for MyFitnessPal and Lifesum, footnotes 3 and 2 list items without a duration in their name. Keto Manager lists $49.99 for its only item named yearly, but two items without a duration cost $29.99, and its Play text names “12 months for USD $29.99”, below Easy Keto (footnote 1). Senza lists no purchases.
- Number of recipes (K7): Easy Keto names 357 recipes. More are named by Carb Manager (with Premium), Keto Manager (with Premium, Play text), Senza, YAZIO, KetoDiet, MyFitnessPal (with Premium Plus) and Lifesum (“thousands”), each per its own statement.
- Limits of the free version (K2): Easy Keto is free to use, but with daily limits, for example 5 entries a day in “My Meals”.

Frequently asked questions
Which keto app is the best?
That depends on what matters to you. This page gives no overall score and no first place: there was no test, and it comes from the provider of one of the apps. If you want to pay little or nothing, look at K2 and K3. If you want no ads and no tracking label, look at K9 and K10. If you want ready-made recipes, look at K7.
Which keto apps are free on iPhone and Android?
All 12 apps on this page are in the US App Store and on Google Play; that is a condition for being included. The sources name a permanently free version for Carb Manager, Easy Keto, FatSecret, Keto.app, KetoDiet, Keto Tracker, Lifesum, MyFitnessPal, Stupid Simple Keto and YAZIO, mostly with limits. Senza is the only app that lists no purchases at all. For Keto Manager, neither store texts nor the provider name a permanently free version.
Is there a keto app without a subscription?
Of the 12 apps on this page, 10 name a free version, which needs no subscription, and Senza lists no purchases at all (see the previous question). A one-time purchase instead of a subscription is in the US App Store list of 4 apps: Easy Keto (“Premium Diamond”, $89.99), Keto.app (“forever”, $39.99), Keto Tracker (“Lifetime”, $79.99) and Stupid Simple Keto (“Premium for Life”, $49.99, or “Lifetime Premium”, $69.99).
How much does a keto app cost per year?
The annual subscription items in the US App Store lists of the 12 apps range from $23.90 to $119.99 (per app in the table); Easy Keto costs $44.99 a year in the US App Store. Many lists contain several annual prices, including offers. The store shows the price that applies to you at checkout.
Is this a test?
No. No app was installed or tried for this page. All information comes from the store pages and the providers’ websites. The page does not show store ratings and reviews, because they are not a criterion with a measurement rule.
Is something out of date?
Email support@easyketo.app, ideally with the source. This also applies to the providers of the other apps. We check the report and correct the table with a new date.
Free to use with daily limits; Premium is optional (annual subscription in the US App Store: $44.99, as of 21 October 2026). Google Play (US) shows in-app purchases of $0.99 to $94.99 per item (as of 21 October 2026, sources).
